In George Orwell’s “1984,” that novel of totalitarian politics whose great mistake was to emphasize the villainy of society’s masters while playing down the mischief of the masses, the goal of communications technology was brutal and direct: to ensure the dominance of the state. The sinister “telescreens” placed in people’s homes spewed propaganda and conducted surveillance, keeping the population passive and the leadership firmly in control. In the face of constant monitoring, all people could do was sterilize their behavior, conceal their thoughts and carry on like model citizens.

This was, it turns out, a quaint scenario, grossly simplistic and deeply melodramatic. As the Internet proves every day, it isn’t some stern and monolithic Big Brother that we have to reckon with as we go about our daily lives, it’s a vast cohort of prankish Little Brothers equipped with devices that Orwell, writing 60 years ago, never dreamed of and who are loyal to no organized authority. The invasion of privacy — of others’ privacy but also our own, as we turn our lenses on ourselves in the quest for attention by any means — has been democratized.

…

Ours is a fragmentarian society, infinitely divided against itself and endlessly disrupted from within by much the same technologies that, in Orwell’s somber novel, assured a dull and deadening stability. In some ways, his nightmare vision of state control is cozy and reassuring by comparison. Big Brother may have stifled dissent by forcing conformity on his frightened subjects, but his trespasses were predictable and manageable. What’s more, his assaults on citizens’ privacy left the concept of privacy intact, allowing the possibility that with his overthrow people might live again as they once had.

Little Brother affords us no such luck, in part because he dwells inside us rather than in some remote and walled-off headquarters. In the new, chaotic regime of networked lenses and microphones that point every which way and rest in every hand, permitting us to train them on ourselves as easily as we aim them at one another, the private and public realms are so confused that it’s best to treat them as identical.
